Continuity mistake: After Carrie rents the car and takes it back, she and Miranda are sitting on the couch talking. As Carrie says something, she turns her head to the right, looking straight at Miranda. When Miranda replies, "Well, that's one option", you can still see Carrie's head in the shot, turned towards Miranda on the right. But then in the next shot of Carrie, she is facing straight ahead and talking in the middle of a sentence.
